In 1972 the newly constructed Homantin Estate included a new primary school. Brother Herman requested the Education Department to grant the sponsorship of the school to the La Salle Brothers. The request was granted.Brother Herman was appointed supervisor and manager of the school. At the start of the 1973-1974 school year the school had a total number of about 2000 pupils in two sessions and a teaching staff of 60 teachers, 4 office staff and 10 cleaners.

In 1973 when a school was built by the Government, the organization in charge of the school was required to cover the cost of all necessary furniture and equipment. The required sum was quite considerable, and more than we could afford. Then Messrs Chan, members of the family of the late Mr. Chan Sui Ki, kindly offered to provide the furniture and equipment for the school on condition that it was dedicated to the memory of their father.We readily acceded to their request and gave the school the name it now has. The school is linked with the foundation of Chan Sui Ki (La Salle) College, which was also sponsored by Messrs. Chan.
